Mennica Legacy Tower

Warsaw, Poland

The Mennica Legacy Tower complex, part of a newly approved master
plan for development in the CBD of Warsaw, is divided into a 35-story tower on
the southeast side of the site and a smaller 10-story building on the west side.
The development features approximately 80,000 square meters of Class A office
space, including a conference center, fitness center and ground-level retail, as
well as four levels of underground parking and ancillary services. A large
plaza between the two structures provides ample space for outdoor seating and a
variety of landscape features.

The taller building has a three-story lobby with a cable-supported
enclosure, utilizing a low-iron glass with a non-reflective coating that blurs
the boundary between interior and exterior space. The tower core is clad with
large stone slabs that accentuate the solid mass of the core, in contrast to
the lightness of the building’s lobby.

The 2,000-square-meter tower floor plate provides an almost
column-free space with 11- to 13-meter lease spans and a 1.35-meter planning
grid. The tower mass features rounded corners on the northeast and southwest
sides that help to reduce the visible length of the east and west facades; on
the opposite corners, the tower incorporates a strong vertical edge.

The southeast and northwest corners are further highlighted by
slightly recessed vertical slots that break up the building’s mass and
introduce an iconic feature. The southeast corner of the tower steps in
three-floor increments outward as it rises, opening the slot to the sky and
creating a dynamic and unique profile that becomes a glowing beacon at night. A
sloping screen wall at the building’s top enhances the profile and integrates
roof terraces into the overall massing. The textured, saw-toothed facades
reinforce the rounded corners and give the enclosure an ever-changing
appearance as one moves around the building.
